Internet for children and teenagers

Of courser now Internet is widespread and it is important for people to get some information, besides it is an easier way. But it can also do harm , especially to children and teenagers.
 Nowadays children are spending hours sitting in front of the computer, busy with some not important stuff. They are chatting in social pages, playing games and spoiling their eyes.
 Now children don't understand how harmful it is.
 Parents should be careful and not to let their children to be busy with computer for a long time. They also forget about their lessons.
In some cases internet is important for getting information you need, especially for your lessons.
They should know how to use it properly ,not wasting time.
They are using internet not only on computer but also with their phone, ipads etc. When they are in front of the computer they don't even understand how the time goes on.
 It is not only harmful for children but also adults. Sometimes they also are sitting in front of the computer, using internet and forget about their work, some other staff they need to do.
I am using internet very often. Both for lessons, and also playing a lot of games. I know that i should use it less. Because of it sometimes i forget about my lessons or don't have any time to do them.
